Question

Which equation does not have the same solution as the others? x + 9 = 14 = 1 6 x = 30 x - 4 = 9

Answer 1

Answer: third equation (x - 4 = 9)

Explanation:

I don't think the one is supposed to be there but, x + 9 = 14, 6 x = 30, and x - 4 = 9 solves to x = 5, x = 5, and x = 13, respectively. So the first two equations have the same solution, while the third equation does not.
